Multilink Ethernet Switch 3.0.0 release notes
Firmware v3.0.0 supports configuration of ports as part of the ring or as non-ring ports N
Faster Rapid Spanning Tree (RSTP) recovery time The Multilink firmware version 3.0.0 has been enhanced to provide faster recovery times when using the RSTP protocol All switches in the network must use the same Firmware revision if any one of the switches contain v3.0.0 or extended recovery times may be observed.
N
Support for the NEW UR Switch module The Multilink Secure Web Management (SWM) interface has been enhanced to support the new UR switch module.
E
Validation of switch IP address during configuration The switch configuration been enhanced to protect against the programming of incorrect IP addresses. When an IP address is entered for the switch, the switch will check to ensure that the address falls within the programmed subnet mask. If the IP address is not within the subnet, the switch will not allow the new IP address to be saved.
N
New Kill Config option for restoring factory default configuration The Kill Config option allows users to selectively restore parts of the switches configuration back to the factory default. Options include: 1) 2) 3) 4)
Return to factory defaults Return to factory defaults but maintain IP and Subnet Mask Return to factory defaults but maintain Port Configurations Return to factory defaults and maintain STP/RSTP settings.
The Kill Config option can be found in the Secure Web Management interface, under Administration and Restore Defaults E
IPv6 address configuration available in Web Management interface The Secure Web Management interface has been enhanced to include IP address settings for IPv6 networks. Previously this setting was only available in the Command Line Interface.
